Academic Mathematics NCERT Class 8

Given: The length of the cloth available$=9\ m^2$ and $16$ scarfs are made from it.

To do: To find the length of the side of the scarf that can be made out of the given cloth.

Solution:

Area of the cloth$=9\ m^2$

The number of square shaped scarfs$=16$

Area of each scarf$=\frac{9}{16}$

Length of each scarf to be made becomes$=\sqrt{0.5625}=0.75\ m$

Thus, $0.75\ m$ of $16$ scarves can be made from the given $9\ m^2$ length of cloth.
